Application filed April 28, 1922, Serial No. 557,207.

vision of a swing designed to seat a number of infants side by side, and in individual chairs so that they can be removed from the swing; without disturbing the others.

Another object is to provide a central seat on the swing; for the use of a maid, or caretaker of the infants, and means for starting the swing to oscillate. to and fro. is provided with the seat and is operated by the feet of the person.

These and other objects will. become apparent in the description below in which similar characters of reference refer to like named parts in the drawing, in which F i gure 1 represents an end elevational view of the swing and is shown in a position of rest. I

Figure the 'SEUIHB.

Figure 3 is a perspective view of'part of the swing platform showing the recesses in is a front elevational view of Y i which the detachable seats are mounted. a

Describing the drawing in detail, the numeral 1 indicates the end support beams which are reinforced by a similar member 2.

' Each of: said beams 1 form a base for the vertical columns 3 and are connected to each other by a truss beam a.

End braces 5 and side braces 6 support the columns 8 and provide a rigid means for preventing excessive swaying of the said column while the swing; is being used.

A swing platform Y is suspended from truss l by stout ropes 8 which have metal rings 9 at the ends and are provided for freedom of movement and reducing friction to a minimum.

Sald' platform 18 of hollow construction and consists of longitudinal side frames 9 joined to each other by the spacers 10 which are providedwith eyelets 12 to which are secured the cradle ropes 13. The lower inter-'- nal edges offramestl have fiangesl l: whlch "swing uses seats lfi. both "feet upon the pedal board 19 and al-' ternately depresses and allows same to rise.

receivethe lower portions of detachable seats 15. The central seat, indicated by the numeral 16, is the operators and has a vertical wall 17 secured to the front platform frame 9. A. platform 18 attached'to the'lowerend i of wall 17 has a foot pedal board 19 pivotally V mounted thereon between the bracketsQO.

A pair of coil-springs 21 are suspended from truss 4- above the operators seat 16;

the lower end having a chain '22 secured" thereto. The chain being securely attached to the'free end of foot pedal 19.

An awning 2-3 attached to a -.roller'24 is:

suspended above the swing platform6 and can be rolled upon roller 24 or retainedin the position shown by Figures 1 and 2. Said roller is mounted, as shown, between the brackets 25 and is oftheusual spring tension type, this enabling the device to be operated during inclement weather, or otherwise forming a sunshade. v

The swing is especially applicable for use in parks orplaygrounds where numbers of small children are wont to spend'their time, I and can be installed .111 any location desired,

after the latterhas been leveled;

In use the children are comfortably seated hen the swing is in; a position of rest the chain 22 is retained at an. angular position soin seats '15 an'dfthe person operatingthe The operator places from its center line of gravity due to "the platform overcoming the weight of the springs 21 and chain 22/ a V v This difference in weight between platform' 7 and chain 22 is equalized by foot pressure uponsaid. pedal 19. Obviously rotating: the latter about its pivot will move the entire platform rearward, so as to allow the swinging body to assume a new position about the changed gravitational center. As

foot pedal 19 is allowed to rise the gravitational center is again changed inducing the platform 7 to swlng forward again. As this operation is successively repeated the said platform will oscillate or swing front to rear in the familiar manner external force.

without the aid of It is to be'understood that certain changes of construction can be made, such as the in-' stallation of anelectrically operated crank arm for swinging the platform, without departing from the spirit and scope of the invention. 3 v

I claim :v 5 A portable swing comprising a pair of supports movable upon a foundation, said supports including rigid uprights, a bean-r fixed between said uprights,-an open, frame disposed longitudinallybetween said up- 10 rights, a plurality of linked rod connections with the eentervseat, a pedal hingedly engaged on said platform, flexible connections beam; and springs interposedin the length of said flexible connections.

In Witness whereof, I affixmy signature;
